aspose.pdf or com.aspose.pdf

Hi ,

I see in the documentation "aspose.pdf(legacy)". Is aspose.pdf a legacy library and we are not supposed to use it ? Is it replaced by "com.aspose.pdf" ?

I see lot of classes may be refactored in com.aspose.pdf with the same behaviour .Are we supposed to use "com.aspose.pdf"  ? Can you please detail what are these two groups and when to use which ?
